Me too. I use my PC as my primary sound system. How much are you looking to spend on a set of speakers? Do you want wireless remote or wired one? The one I have is a kick ass system but cost a little over $200. It comes with a wireless remote control for volume, surround settings, other sound settings, input/output.

There are cheaper version of that but comes with a wired remote. But the purpose is to have a wireless one which is much better.
